YARN-GUIDING DEVICE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 386,975, dated July 31, 1888.

Application filed December 7, 1887. Serial No. 257,203.

To aZZ whom it may concern:

Be it known that I, JOHN F. FoLLE'rT, acitizen of the United States, and a resident of Central Falls, county of Providence, State of Rhode Island, have invented new and useful Improvements in Yarn Guiding Devices for Spinning-llIachines, of which the following is a full and exact description, reference being had to the accompanying drawings, making partof this specification.

This invention relates to improvements in spinningmachines, and more particularly to the guide-plates thereof, and has for its objects to provide guide-plates which may be independently adjusted with rapidity and ease, and to mount the same on a rocking shaft in such a way as to be raised or lowered simultaneously by the rotation of the shaft, and to provide a means for retaining the shaft in the position in which the plates are raised.

To these ends it consists in the construction and combination of the parts described and claimed in the following specification.

In the drawings, Figure 1 is a plan view of the invention attached to the roller-beam of a spinning-machine. Fig. 2 is a front elevation of the same. Fig. 3 is a detailed View of one of the guide-plates. Fig. 4 is a perspective view ofamodified form. Fig. 5 is a detail view of the handle controlling the shaft and the hearings in which it is mounted.

The letter A designates the rocking shaft, The said shaft is extended the entire length of the roller-beam, and is mounted in bearings B B, as may be required, at intervals on the rollerbeam. Attached firmly to the said shaft is the doffing'handle C. The said handle is pro vided upon the under surface with a cam, D, which, when the said handle is raised to a horizontal position, binds upon the bearing B, in which the said handle is mounted, holding the shaft A in position to allow for doffing. The said handle may be mounted at the end of the shaft A or in the center of the same, the latter construction being preferable when the said shaft is long.

Mounted upon the shaft A, at intervals regulated by the spindles, are the guideplates E. The said plates consist of a flat body, F, the guide-rod I, and the clamp H. The said body is constructed of thin metal, so that the action (No model.)

of the same will be light. At the forward end it is provided with a guide-rod, I, extending from a perforated lug upon its under surface, and at the rear end with the hinge-wings K K. The said guide-rod consists of a piece of stiff wire bent to a complete coil at the end, forming an eye for the thread to pass through, and is provided at the other end with a screwthread adapted to engage the thread in the perforation ofthe lug upon the body F, wherein it is screwed rigidly, extending out beyond the said body.

The clamp H is provided with the hingewings M, which fit between the wings K K upon the body F, and are provided with the shoulders N at the rear, which prevent the said body from turning completely over. The said clamp is attached to the body by passing the rod 0 through a perforation provided in the said wings M and K. In the under surface of the said clamp is formed the curve P, which conforms to the curve of the shaft A and fits the same snugly. At the rear of the said curve the clamp is provided with the shoulder It, having at the end the upturned point V, upon which the body F normally rests. The shoulder R is provided with a threaded perforation, by means of which the elamping jaw S is secured thereto by the screw T. The said clamping-jaw [its flush with the under face of the said shoulder, and is provided with the curved extension U. The said extension is mounted over the curved shaft, and is adapted to impinge upon the shaft A when screwed down upon the shoulder It.

In mounting the guide-plates upon the shaft A the screw T is turned so as to free the said clampingjaw S, allowing the said shaft to be placed in the curve P. The extension U is then brought over the said shaft and forced down upon the same by the screw T, binding the said shaft between the curve P and the extension U, thus fixing the plates firmly upon the shaft. To remove the same the operation is reversed.

\Vhen the parts herein described are mounted as shown in the drawings, they may be operated for doffing the spindle by catching the handle (I and raising the same. This throws the clamp II around with the said shaft, which raises the guide-plates E,allowing the spindles to be doffed. In this position the shaft A is held firmly, with the guide-plates raised, by the cam D of the handle 0 binding upon the bearing B, as hereinbefore described. The said guideplates are so constructed that when raised upon the shaft in the position just described they are balanced thereon, and need but little force to retain them in position when so raised.

When the spindles have been doffed and the bobbins replaced thereon,the said guide-plates are brought into position by lowering the handle Oand moving the said guide-plates offtheir balance, when they fall to the horizontal position shown in Figs. 1 and 2 of drawings, where they rest upon the points V of the clamp H, and the frame is then ready for operation.

When the ends of the th read break, as they frequently do when spinning. by means of this construction the guide-plates can be raised by the operator singly, allowing thereby the removal of the spool to piece up the end, and when so pieced the spool may be replaced and the operation resumed by allowing the guideplate to fall into position. This it must do,as it cannot be raised enough to balance when the shaft A is in position to throw the said plates over the spools, being prevented from so doing by the shoulder N of the clamp H.

In the modified form shown at Fig. 4 of drawings I have built upon the lowerside ot' the shoulder B so as to extend it below the shaft A. Through this part I have provided a threaded perforation on a line slightly below the center of the said shaft. In this perforation I have mounted a screw, which engages the threads in the perforation in the shoulder R and impinges upon the shaft A. The guideplates, when provided with this modification, are seen red by placi ng the clamp over the shaft A and driving the end of the screw against it, which holds them firmly in position.

What I claim is-- 1. A guide-plate provided with the clamp H, having the groove 1?, the shoulder R, the clamping jaw S, provided with the extension U, adapted to impinge upon a shaft fitted in the groove 1?,and the screw T, passing through a perforation in the shoulder R, substantially as described.

2. The combination of the shaft A, the han- JOHN F. FOLLETT.
